Hi Marcus, and welcome to Talk Morgan and the Three Wheeler forum in particular, I am sure you will spend many happy hours here, and more importantly, make some great friends.
One of the best 'features' of the Morgan Three Wheeler is its' simplicity, which, in practice means that it is easy to modify and adjust just about everything, and the seats are one of the simplest things, as they are just pieces of plywood, with foam and leather on. They can be spaced out, recessed back lifted at the front or back and moved in and out at will, with no more than a few blocks of wood.
As Roger has said, pedals can be moved, and Colin has alluded to the fact that steering wheels can be changed, so don't let little things like not finding a comfortable position in the demonstrator hold you back, get you order in ASAP, so your car is ready in time for next spring. All you need to worry about just now, is getting a build slot allocated, you can then spend many happy hours deciding how to enrich the MMC from the options list [my car was bog standard, you won't be surprised to hear], and keeping in touch via this forum, and ask all the questions you like, there will always be an answer, and possibly a little rib tickling too, if you don't mind?
